ABSTRACT

OBJECTIVE: The sacroiliac joint can be a primary source of pain or part of multifactorial syndromes. As there is no single historical, physical examination-based, or radiological feature that definitively establishes a diagnosis of sacroiliac joint pain, diagnostic blocks are regarded as the gold standard. The primary aim of this randomized trial was to compare the posteroanterior approach with the classic oblique approach for sacroiliac joint injection based on an assessment of procedure times and patient-reported pain outcomes in subjects scheduled for fluoroscopically-guided sacroiliac joint injections. METHODS: Thirty patients were randomized into 2 groups of 15 patients each. The endpoints measured included the total length of procedure time, fluoroscopic time, needling time (length of time the needle was maneuvered), and pre- and postprocedure visual analogue scale pain scores. RESULTS: The posteroanterior approach was significantly shorter in terms of procedure time (p=0.03) and needling time (p=0.01) than the oblique approach. Adjusting for body mass index, the mean procedure and needling times were significantly shorter in the posteroanterior group than in the oblique group. CONCLUSION: This study of the posteroanterior approach for fluoroscopic-guided sacroiliac joint injection observed shorter times for fluoroscopy, needling, and the overall procedure than were recorded for the widely prevalent oblique approach. This may translate to lower radiation exposure, lower procedural costs, and enhanced ergonomics of fluoroscopicallyguided sacroiliac joint injections.

ABSTRACT

OBJECTIVE: Lower back pain (LBP) is a worldwide health problem, and magnetic resonance imaging (MRI) is a common modality used to aid in its diagnosis. Although specific guidelines for assessing the necessity of MRI usage exist, the use of MRI as the initial imaging method for LBP seems to be more common than necessary in general practice. METHODS: We conducted a retrospective chart review of 313 patients who had undergone MRI of the lumbosacral spine during 2014-2015. We recorded and compared various factors, including age, sex, body mass index, current smoking status, race, symptoms, MRI findings, and progression to surgery within the next year. All rates were compared according to whether the MRI results showed radiographically significant findings (MRI-positive) or not (MRI-negative) using the chi-square or Fisher exact tests (if the expected cell count was <5). All analyses were performed using SAS version 9.4. RESULTS: There were no statistically significant differences in the rates of each symptom between the MRI-positive and MRI-negative groups, which accounted for 58.5% (183 of 313) and 41.5% (130 of 313) of the MRIs, respectively. The difference in the rate of surgery in the next year (18% among MRI-positive patients and 8.5% among MRI-negative patients) was found to be statistically significant (p<0.05). CONCLUSION: Based on our findings, 41.5% of patients underwent lumbar MRI unnecessarily and 81% of patients with positive MRIs did not have surgery within the next year. Further physician training is needed to avoid unnecessary investigations and expenditures.

ABSTRACT

Objective: To determine the risks of continuing or ceasing anticoagulant or antiplatelet medications prior to image-guided procedures for spine pain. Design: Systematic review of the literature with comprehensive analysis of the published data. Interventions: Following a search of the literature for studies pertaining to spine pain interventions in patients on anticoagulant medication, seven reviewers appraised the studies identified and assessed the quality of evidence presented. Outcome Measures: Evidence was sought regarding risks associated with either continuing or ceasing anticoagulant and antiplatelet medication in patients having image-guided interventional spine procedures. The evidence was evaluated in accordance with the Grades of Recommendation, Assessment, Development, and Evaluation system. Results: From a source of 120 potentially relevant articles, 14 provided applicable evidence. Procedures involving interlaminar access carry a nonzero risk of hemorrhagic complications, regardless of whether anticoagulants are ceased or continued. For other procedures, hemorrhagic complications have not been reported, and case series indicate that they are safe when performed in patients who continue anticoagulants. Three articles reported the adverse effects of ceasing anticoagulants, with serious consequences, including death. Conclusions: Other than for interlaminar procedures, the evidence does not support the view that anticoagulant and antiplatelet medication must be ceased before image-guided spine pain procedures. Meanwhile, the evidence shows that ceasing anticoagulants carries a risk of serious consequences, including death. Guidelines on the use of anticoagulants should reflect these opposing bodies of evidence.

ABSTRACT

UNLABELLED: Percutaneous radiofrequency ablation (RFA) of the sphenopalatine ganglion (SPG) has been shown to be an effective modality of treatment for patients with intractable chronic cluster headaches (CHs). While the use of fluoroscopy for RFA of the SPG is common, to our knowledge there are no documented cases of procedures using cone beam computed tomography (CBCT) for image guidance. We present a case report of a patient suffering from chronic intractable CH with complete long-lasting relief after RFA of the SPG using CBCT. The case reaffirms the potential efficacy of RFA of the SPG in a case of chronic cluster headache as well as the use of CBCT as a superior alternative to bi-plane fluoroscopy for image guidance in the management of chronic CH. KEY WORDS: Cone beam computed tomography, sphenopalatine ganglion block, cluster headache, interventional pain, autonomic cephalalgia, radiofrequency ablation.

ABSTRACT

Epidural steroid injections are a common procedure performed by pain physicians. The American Society of Regional Anesthesia along with several other groups recently provided guidelines for performing epidural injections in the setting of anticoagulants. We present a case of a patient who developed an epidural hematoma and subsequent paraplegia despite strict adherence to these guidelines. Although new guidelines serve to direct practice, risks of devastating neurologic complications remain as evidenced by our case.

ABSTRACT

Transient global amnesia (TGA) is a well-described neurological phenomenon. Clinically, it manifests with the sudden onset of a paroxysmal, transient loss of anterograde memory and disorientation but with intact consciousness. Typically, symptoms last for only a few hours. We present an unusual case of aortic dissection presenting with pure TGA in a patient, who had a positive outcome. This is the second case report of a patient with aortic dissection presenting with pure TGA syndrome, but it is the first case in which the patient survived.

ABSTRACT

OBJECTIVE: To report a case of hiccups secondary to intrathecal (IT) morphine infusion. METHODS: Case report and discussion. RESULTS: The hiccups in our patient resolved on substitution of IT morphine infusion with hydromorphone. DISCUSSION: We report a case of a 44-year-old man who developed persistent hiccups with IT morphine infusion pump therapy. The hiccups persisted despite various nonpharmacological and pharmacological measures. The untoward symptom resolved after substitution of IT hydromorphone for IT morphine.
